Information Assurance
Integrity

- Quality of information system
- Logical completeness of hardware and software
- Consistency of the data structures and occurrence of the stored data

In computer security considerations, integrity basically means employing measures designed to protect against unauthorized modification or destruction of information. Unauthorized access to your computer can lead to integrity problems. For example, someone could alter the data in your file unintentionally by entering a wrong number or letter. Someone who desires to do harm and defeats system protection can add widespread or subtle changes, according to their purposes.
